THEORETICAL considerations suggest that the square root of mass may be more interesting and important than mass itself in the case of the ultimate particles of matter. For in the modern theory of matter, electric charge is more fundamental than mass, and the dimensional formula for electric ...
where E0 is the peak amplitude of the laser field, q and m are the electron charge and mass, and ω is the angular frequency. Recombining trajectories are found by setting x(trec) = 0. They have a photon energy of Ω = Ip + 0.5(dx/dt)2. The resulting cut-off is ...
In electron impact mass spectrometry, the collision of a high energy electron with a sample molecule produces a radical cation, M+·. The first ion that forms in this process is the parent ion. Since the charge of the ion is +1, and since the mass of an electron is much smaller than...

Experimental charge density modeling of a magnesium dimer complex and subsequent topological analysis reveals the existence of a chemical bond between the two central Mg atoms. Analysis of the molecular system using the energy density, the source function, and several density profiles along the entire...
Temperature-dependent charge-carrier transport between Si-δ-doped layers and AlGaAs/InGaAs/AlGaAs quantum well with various space layer thicknesses measured by Hall-effect analysis Temperature (=40~300K) dependence of Hall-effect analysis on the dual Si-δ-doped AlGaAs/InGaAs/AlGaAs quantum-well (...
Wevelength-dispersive X-ray spectroscopy (WDS) differs from EDS in the change of charge carriers in the detection device. In WDS, only one element can be analyzed at a time while EDS gathers a spectrum of all elements, within limits, of a sample. Sensitivity is 100ppm (0.01wt.%) with ...
mysterious mass ratio between the proton and electron of ~1836. In this paper it is shown that the mass-energy of the proton is equivalent to the vacuum energy excluded by a spherical shell with an average radius equal to the charge radius of a proton. Likewise the electron mass is shown...
While beam deflection-based approaches (e.g., DPC)25 have been used to image the charge density and associated electric fields in materials, these approaches report on the total charge density, including contributions of the atomic nuclei. Considering only secondary electrons generated through impact...
The relationship between electron–phonon (e-ph) interactions and charge-density-wave (CDW) order in the bismuthate family of high-temperature superconductors remains unresolved. We address this question using nonperturbative hybrid Monte Carlo calculations for the parent compound BaBiO3. Our model inc...
